Constructor Details

StandardOperatorTable2

public StandardOperatorTable2()

Create the standard set of operators. Calls setBasicPfmcs(), setSpecialPfmcs(), setPsudoPfmcs().

StandardOperatorTable2

public StandardOperatorTable2(OperatorTable2 oldTable)

Decorator constructor. Shares the same set of operators as the argument and calls setBasicPfmcs(), setSpecialPfmcs(), setPsudoPfmcs() to assign new PFMC's to the operators.

Parameters:

oldTable - base table

StandardOperatorTable2

protected StandardOperatorTable2(Map<EmptyOperatorTable.OperatorKey,Operator> oldTable)

Constructor with pre-specified table of operators

Parameters:

oldTable -

Method Details

setBasicPfmcs

protected void setBasicPfmcs()

Sets the standard set of pfmc's for basic operators. This method is called by the constructor and subclasses can override this method to change or prevent building of these pfmcs.

See Also:

• OperatorTable2.BasicOperators

setSpecialPfmcs

protected void setSpecialPfmcs()

Sets the standard set of pfmcs for special operator: assignment, dot product, cross product, the list operator and the element-of operator. This method is called by the constructor and subclasses can override this method to change or prevent building of these pfmcs.

See Also:

• OperatorTable2.SpecialOperators

setPsudoPfmcs

protected void setPsudoPfmcs()

shallowCopy

public OperatorTableI shallowCopy()

Description copied from class: EmptyOperatorTable

Create a new version of this OperatorTable. Operators are copied into new table. However, Operators whose pfmc implement JepComponent are duplicated. This means the table could be used in a separate thread without problem. Subclasses should override with method to return a table of the correct type, a typical implementation would be

    @Override
    public OperatorTableI shallowCopy() {
        Map<OperatorKey, Operator> map = this.threadSafeMapCopy();
        return new MyOperatorTable(map);
    }
 

using the EmptyOperatorTable.threadSafeMapCopy() method to return a copy of the map of operators and a constructor taking this map which uses the EmptyOperatorTable(Map) constructor.

Specified by:

shallowCopy in interface OperatorTableI

Overrides:

shallowCopy in class OperatorTable2

Returns:

a new Table
